2005 f150 4X4 what fluid for tranny/ifferential/trxfr case

peanstein · #1 01-07-2008, 09:24 PM

ok, what do you recommend on a 2005 4X4 f150 for tranny/dfferential /ransfer case service?

i bought it used with 31K and now has 45K
i have only changed the oil and oil filter as well as the fule filter. oh air too.

i have not off roaded and occasionally engage the 4x4 for a minute or so to activate it only.

what should i do in respect to the fluids for the tranny/dfferential /ransfer case fluids? if replacement is recommended, what type should i use? nothing fancy needed. what filters, if any, should be replaced as well?
thanks and i have looked in the manual for recommnedations but would like others opinions that have done it.

thanks

victor

i have fluid types / specs from a 2000 F150 4x4 but they may not be the same, if you want them let me know. sorry i don't have info on 2005

you may want to pick up a service manual that will give you all specs / fluid types for your 2005, i have one on my 00

Amsoil ATF for tranny and transfer case. Amsoil 75W140 for the rear axle and 80W90 for the front. Don't forget to throw in a bottle of friction modifier in the rear axle.

Diffs and transfer case should be good for 100k. Just keep the tranny fluid changed every 30k or so.
